I need to make some chocolate shells for a mermaid cake. whenever I use the moulds, the shells don't come out nice and shiny, they kind of lose the top. are there any tips on making them nicer.

Thanks
Dina

are you putting them in the fridge to set?

I throw mine in the freezer for a few minutes and pop them right out

by the sound of your issue, you are either not putting them in the fridge/freezer, or not loeaving them in long enough

No, I wasn't putting it in the fridge or freezer to set. I will try that and see how it goes.
Thank you for the tips

Are you using chocolate or confectioner's coating/candy melts? If you are using real chocolate, then your problem is most likely your temper. If you do not properly temper, your chocolate will not be shiny.

So should I use chocolate melts instead? I was using lindt chocolate

Lindt chocolate bars?

No, I buy the baking chocolate from them. They come in a large bag and look like little chocolate dollars.
